Pros
- Saves tabs in large amounts
- Good amount of customization for the addons
Cons
- Will delete your entire tab list without warning or reason
- Lack of transparency makes it hard to recover tabs without exporting regularly

Works on my Android phone (Samsung) and so far is the best extension on FireFox for grouped tabs. However, even if they add that feature to FireFox mobile this add-on will STILL be useful since you can actually save and completely put aside tabs and have a clean tabless page when needed while still having saved tabs. Absolutely incredible.

Dev, please figure out what is wrong with your add on. Since Firefox updated my tabs vanished and appear to have been replaced by a sidebar added to Firefox that performs a similar function but not as well as OneTab did.

Perhaps OneTab being in the same location as the sidebar Firefox added is the cause of conflict? Auto Tab discard is functional and it does not use this same area. Tab Session Manager also works fine so that was the only logic I could think of. I love using this add-on and hope you'll take time to sort this out as it was the reason my computer RAM was being drained entirely and had been crashing out. I had to remove it to make that stop.

PLEASE fix, I'd love to use it again and I hate what Mozilla has done to replace it with their own sidebar. Can't you relocate this add on to the other side of the browser bar? Thanks for considering my request and I wish you the best of luck in this effort.

It doesn't open anymore

這是一個簡單易用的好東西，
直到Firefox大更新前都是。
今天大更新後，我的資料被清空了，
嘗試許久也救不回來，
是時候，該放棄這套工具了。

這套工具幫助了我許多年，
還是謝謝你作者。

Excellent way to organize my study searches and save memory and CPU

No cloud or sync

Good extension, does everything that an AddOn like this should do.

To all those who write that all of your data is lost in onetime.
Have you tried making a backup locally on the hard drive, after 100 pages saved in OneTab? Or do you all think that you can save an infinite number of pages without the memory running out?😒

very simple and easy to use

All of my saved pages randomly disappeared.
